A recent merge request corrected several spelling errors in VTK-m.
One such correction was in the git-gitlab-sync script in the
Utilities/GitSetup directory. This commit reverts the change in
this specific file for two reasons.
1. The changed introduced a \' inside a single quote string (to
correct cant to can't). However, single quotes in shell scripts
do not allow you to escape characters like that, and thus this
causes an error when running the script.
2. This script actually comes from a separate repository
(https://gitlab.kitware.com/utils/gitsetup) that we occasionally
syncronize with. To prevent confusion, we should minimize the
divergence between this repository and that one. If someone wants
to make this change, it should really be made in the GitSetup
repository.
Specifically, several of the git setup scripts defined a function
named "egrep-q". This almost always works, but I happened to have
an install of git on windows/cygwin that gave the error:
`egrep-q': not a valid identifier
I always thought hyphens were allowed in script identifiers (and
usually they are), but apparently sometimes they are not. (See
for example
https://stackoverflow.com/questions/2821043/allowed-characters-in-linux-environment-variable-names).
This provides an easy fix by replacing egrep-q with egrep_q.
