# 20210910 bkw: if someone tries to use a decimal as a factor,
# e.g. 1.5, bdfresize silently ignores the .5 and treats the argument
# as just 1. This patch adds a check to make sure the factors consist
# only of digits and 0 or 1 slashes. Patch is by the SlackBuild
# author, who keeps trying to say "-f 1.5" despite all sanity...
