Subject: mkrules: Handle multiple files with the same metrics.
X-Git-Url: https://git.distorted.org.uk/~mdw/xfonts-traditional/commitdiff_plain/fe6a7d791ffe20cb0cf74a22e2c024dc6319574e

mkrules: Handle multiple files with the same metrics.

If we had two PCF files with the same metrics previously, we'd overwrite
the rules file from the first with a new file from the second.  Keep
track of which files we've written during the run, and append to them if
we've already started writing.  Finish them all up at the end.
