Re: implementing pre-commit-hook to prevent overwriting files under tags-dir

After getting the pre-commit script to run, I noticed that the logic is not
working as expected.

When I try committing a change of a file that resides under tags, the script
should identify that, output an error-message and exit with code 1. But this
doesn't work.

Here is the relevant snippet:

TAGS_REGEX='tags/[^/]\+'
# Get list of transactions in the 'tag' directory
TAGS_CHANGES=`"$SVNLOOK" changed -t "$TXN" "$REPOS" 2>/dev/null | \
                 awk '{ print $2; }' 2>/dev/null | \
                 grep ^tags/ 2>/dev/null | \
                 sed -e "s!^\($TAGS_REGEX\).*!\1!" | \
                 sort | \
                 uniq`

I figured out, when I commit a file, the variable TAGS_CHANGES is empty.

The command
$SVNLOOK" changed -t "$TXN" "$REPOS"
prints out the list of committed files properly. LIke
U project/tags/1.1.1/file.xml

The bug must be somewhere else.
