Hi People,

In one word, the regexp (a|) is not portable.  mawk hates, gawk loves.
Completion of make is affected on all the debian systems.

\? is portable.

According to one of the most aesthetic regexp I ever had to write:

share/zsh/functions # egrep '(\(\||\|\))' -- `fgrep awk -il *`   nostromo 18:15
_make:          /^\.include  *<bsd\.port\.(subdir\.|pre\.|)mk>/ || /^\.include  *".*mk\/bsd\.pkg\.(subdir\.|)mk"/ {
_mh:elif [[ "$prev" = -(no|)cc ]]; then
_zftp:  *(get(|at)|gcp|delete|remote))
_zftp:  *(put(|at)|pcp))

Only _make was affected, the others were not awking in the
corresponding section.

Regards,

        Akim
