           Summary: -M changes order of records in hg log
          Severity: bug
    Classification: Unclassified
                OS: Windows
          Reporter: peterhull90 at gmail.com
          Hardware: PC

           Version: 3.0.1

If the -M flag and an explicit revision range is given to hg log, the order can
be reversed compared to what is expected.

Example: (taken from Matt Mackall's reply to the list)

Observed: 
$ hg log -M -q -r 10:9
9:b4d0c3786ad3
10:e76ed1e480ef

Expected:
$ hg log -M -q -r 10:9
10:e76ed1e480ef
9:b4d0c3786ad3

Further information:

# Correct on version 2.9 (i.e. this is a regression from previous)
$ hg29 log -q -M -r 10:9
10:e76ed1e480ef
9:b4d0c3786ad3

# Correct on current version without -M
$ hg log -q -r 10:9
10:e76ed1e480ef
9:b4d0c3786ad3

# Correct on current version with a revset
$ hg log -M -q -r "(10:9)"
10:e76ed1e480ef
9:b4d0c3786ad3

# Correct on current version with -M in revset
$ hg log -q -r 'not merge() and 10:9'
10:e76ed1e480ef
9:b4d0c3786ad3

Work around:
Use a revset, i.e.
$ hg log -M -q -r "(10:9)"
