Almost. The handling of compressed pages as far as man --recode vs.
man-recode is much the same: both of them optionally accept compressed
input and always emit uncompressed output. However, with man --recode,
dh_installman effectively did the following (I've removed the directory
parts of paths to make it easier to read):
man -l --recode UTF-8 makeweights.6.gz >makeweights.6.gz.dh-new
# makeweights.6.gz.dh-new is in fact uncompressed, despite the .gz
rm -f makeweights.6.gz
mv makeweights.6.gz.dh-new makeweights.6
... but with man-recode, it tries to do:
man-recode --to-code UTF-8 --suffix .dh-new makeweights.6.gz
# writes uncompressed page to makeweights.6.dh-new
rm -f makeweights.6.gz
mv makeweights.6.gz.dh-new makeweights.6
I'd suggest something like the following *untested* patch, which both
makes $manpage_tmp make more sense in man --recode mode and should make
it work properly in man-recode mode by bringing it into sync with the
actual output file names.
