Subject: Fix undersample option accepting 0
X-Git-Url: https://git.ljiriste.work/?a=commitdiff_plain;h=793897be15bdf4ec3bfb09767d8692cc8944b802;p=42%2Ffract-ol.git

Fix undersample option accepting 0

When -u 0 is specified, it leads to an infinite loop.
The window is then unresponsive which is clearly a bug.
Now the -u 0 option emits a help message.
