Hi
I stumbled upon a bug in the doxygen syntax file
(runtime/syntax/doxygen.vim) in Vim-7.3.353 which
causes anything after /***/ to be incorrectly highlighted
as a cComment.
Steps to reproduce:
1) Create a file foo.c and edit it with vim as follows:
$ cat >foo.c <<EOF
int foo(void)
{
/***/
bar();
}
EOF
$ vim -u NONE -c 'let g:load_doxygen_syntax=1|syntax on' foo.c
2) Observe that 'bar();' is highlighted as a cComment which
is wrong. Anything after /***/ is incorrectly highlighted
as cComment.
It happens with /***/. It does not happen with /**/ or /****/.
Attached patch fixes it.
Regards
-- Dominique
