Apparently, ctags applies the rules before deleting comments:
ctags: Warning: include/linux/completion.h:22: null expansion of name pattern
"\2"
Work around this particular case by requiring the group to contain at
least one character. Leave the other patters as they are, until a better
solution is found.
