Is there a case where test_i18ngrep (after your clean-ups in this
series up to 06/10) needs to read from more than one file?
I actually think that the kind of inconveniences we *can* work with,
without risking breakage to legitimate test, would be to allow and
require test_i18ngrep to name and read only from one file that
appears at the end of its command line. IOW, instead of doing a
probing "read" that you cannot undo and break legitimate test, I
think it is OK to see if the last token names a file that is on the
filesystem, e.g.
test_i18ngrep () {
eval test -f \"\${$#}\" ||
error "bug in the test sript: test_i18ngrep must" \
"name a file to read as the last token on the command line"
...
