main: quote output file name before passing it to system(3) function
|
||||
|
||||
Following command line doesn't work:
|
||||
|
||||
$ ctags -o 'a b' ...
|
||||
|
||||
because a shell lauched from system(3) deals a whitespace between 'a'
|
||||
and 'b' as a separator. The output file name is passed to system(3)
|
||||
to run external sort command.
|
||||
|
||||
This commit adds code to put double and single quoets around the output
|
||||
file name before passing it to system(3).
|
||||
|
||||
The issue is reported by Lorenz Hipp <lhipp@idealbonn.de> in a private mail.
