[p4] Can you find out which changelist your workspace has beensynced to?

[Dave Lewis]

interesting.  some time ago, when this command did not run so efficiently, I
used to do this by doing a p4 files //myworkspace/... and finding the
highest changenumber.  You need to check that you are using the right form
of the files command to get what you want.

best is to just sync to a known changelist number, and record that in a
file.
