mq: fix qpop of working directory parent patch when not at qtip
mq assumed that it had to update from qtip to qparent, and instead of updating
from where it was it failed with:
abort: working directory revision is not qtip
largefiles: make log match largefiles in the non-standin location too
Yet another match hack.
log: make log work even if first parameter doesn't exist
A slowpath optimization kicked in too often because of wrong indentation.
merge: remove "case" comments
The comments introduced in
f05c182430a0 seems important ... but the context has
apparently been lost and they do not have any value now.
