The current pause functionality simply removes all the autocommands to
stop updating Tagbar. This has the problem that at the moment the
statusline functions immediately restore the commands so pausing doesn't
work, but even if that didn't happen it would stop the statusline
functionality from working which is not desirable. The solution is to
have a reference to the paused file which will get used by the Tagbar
window, but not the statusline functions.
Certain quickfix-commands like vimgrep have to load all searched files
into Vim and will execute the BufReadPost autocmd for all of them. Since
Tagbar doesn't need to generate tags for those files pause processing
while the command is running.
There doesn't seem to be a better way to find out whether vimgrep is
running than to set a temporary variable with the QuickFixCmdPre/Post
autocmds, see also

Closing Tagbar with :q instead of the provided commands and mappings
would bypass the Vim application window shrinking logic. Install an
autocommand that checks for this situation.
This prevents files being processed twice unnecessarily, once for
FileType and once for BufReadPost. All cases where BufReadPost is called
without FileType should be covered by the checks in AutoUpdate().
a:ctags_bin calls a batch file that uses %~dp0. Changes include:
- Enable ctags_args to be a list
- Changed default ctags_args to be a list to improve robustness of
s:EscapeCtagsCmd()
- Do not escape 0th argument of ctags_cmd for cmd.exe when it is not
necessary because otherwise batch files may not return expected value
for %~dp0
- Updated tagbar documentation about string and list value types for
ctags_args
See https://github.com/majutsushi/tagbar/issues/133
Since the window numbers can change when opening and closing windows
Tagbar so far has used bufwinnr() to find the right window to jump back
to. However, this fails if the same file is being displayed in more than
one window. Save a window-local variable instead to detect the correct
window to jump back to.
If a ctags-compatible program returns an error status code on a parsing
failure then it would never be run again on the same file, even if later
invocations would have returned normally (for example after fixing an
error in the current file). Therefore we need to execute the program on
updates as usual, but do not repeat error messages if the previous run
already did.
