Initially, I did this,
git grep -l srcdir/test-lib.sh|xargs perl -p0i -e '~180-byte script'
but that line would have been much longer than the maximum permitted
by coreutils' commit hook, and wasn't readable besides, so here's a
more readable version:
lhs=$(printf '%s\\n' \
'if test "$VERBOSE" = yes; then' \
' set -x' \
' touch --version' \
'fi' \
'' \
'. $srcdir/test-lib.sh' \
| sed 's/\$/\\\$/g;s/touch/(\\w+)/')
rhs=$(printf '%s\\n' \
'. "${srcdir=.}/init.sh"; path_prepend_ ../src' \
'test "$VERBOSE" = yes && FIXME --version' \
| sed 's/\$/\\\$/g;s/FIXME/\$1/')
git grep -l srcdir/test-lib.sh|xargs perl -p0i -e "s,$lhs,$rhs,"
