As pointed by Coverity, if the Keysym name is very long and many modifiers
are used, the function 'capture_shortcut' could overflow its internal
buffer.
As the case is very unlikely to appear, do not increase the size of the internal
buffer (it seems to be already well sized, and we have no know maximum size
for a Keysym name), just use the appropriate function to append the name
at the end.

Unfortunately this will lower the translation score for German, but the
translation guessed by fuzzy matching in gettext is not acceptable in the
current case: the translated string is already used for another entry in
the list, meaning that user would not see the difference between the two
and would probably then not understand why things do not behave the way he
expects.

As pointed by Coverity, the sizeof used was not done on the right type.
This worked because the element was a pointer all pointers types have the
same size in most platforms.
For code maintainability, the code will now take the size from the first
element of the array to be sorted, so that if the structure gets changed
someday the expression will stay valid.

There is a check a few line above that already return from the function
because there is nothing to do for that case, so the case statement cannot
be reached. As not all case are covered in that switch anyway that won't
make a difference, and because an 'int' is used instead of an 'enum' the

As Coverity pointed, when building the command line to execute the current
code just assumed that it would fit in the large buffer. If user were to
provide a line too long, this would crash.
Factually this is probably not possible at current time because the command
given to the function was actually already limited to the MAXLINE size when
it was read, but this may not be guaranteed in future evolution.
Better safe than sorry, so the patch implement a size check when appending
strings, using a more efficient method (strcat re-parse the destination
string from the beginning to find its end every time).
Took the opportunity to:
- not include a trailing space at the end of the command
- do not run command if it was truncated (it could be a problem) but
provide a message to the user about it, so he may fix the problem

anyway), but avoid allocating in first place if it is not necessary.

There was a probable bug when reading settings, because the function used
was 'getInt' which would try to store the result in a 'char'. As it would
be probably easier for user to have the value directly in pixels, the
storage is now done in an int so there won't be problem anymore.
Changed the behaviour of the constant APERCU_BORDER, which would be assumed
to be the size of the border in pixel, but in previous code it was actually
the sum of the two border (1 on each side). All maths have been changed to
have it as a single border width.
Took opportunity to group variable assignation for titleHeight and

A type conversion applied to a function when used as a pointer is dangerous
because the compiler may not be able to make sure arguments will be
compatible across architectures, so it can crash the application.

the function so the compiler have complete liberty to generate any code

The function is building strings from the directory names into an allocated
buffer, but the function took time first to calculate the exact size needed
for the resulting string, so the check on wstrlcat's result will never

just return a truncated string in the list instead of return no list at all
but the case where it would happen is impossible.
