hg qrefresh doesn't honor "--encoding" for "--logfile"

[Marc Strapetz]

It seems that:

 hg qrefresh --encoding utf-8 --logfile <file>

still tries to process the log-file with platform encoding. When using:

 hg commit --encoding utf-8 --logfile <file>

with the same <file>, contents are properly interpreted as UTF-8.
