patchbomb: normalize date format in generated mboxes
mbox format should use time.asctime(). Unfortunately, this function writes
2-characters day of week on Windows while unix one writes a single character.
Normalize to Windows version since the other one can hardly be written with
strftime().
#!/bin/sh
hg init a
cd a
hg log
hg grep wah
hg manifest
hg verify
ls .hg
ls .hg/store
cd ..
hg clone a b
cd b
hg verify
