rebase: reinstate old-style rev spec support for the source and base (issue3181)
As of b12362ab13e7 (first released as part of Mercurial 2.0), the rebase command
accepted ONLY revsets for the source and base arguments and no longer accepted
old-style revision specifications. As a result, some revision names were no
longer recognised, e.g.
hg rebase --base br-anch
abort: unknown revision 'br'!
These arguments are now interpreted first as old-style revision specifications,
then as revsets when no matching revision is found. This restores backwards
compatibility with releases prior to 2.0.

'''browse command output with an external pager To set the pager that should be used, set the application variable:: [pager] pager = less -FRSX If no pager is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager is used. If you notice "BROKEN PIPE" error messages, you can disable them by setting:: [pager] quiet = True You can disable the pager for certain commands by adding them to the pager.ignore list:: [pager] ignore = version, help, update You can also enable the pager only for certain commands using pager.attend. Below is the default list of commands to be paged:: [pager] attend = annotate, cat, diff, export, glog, log, qdiff Setting pager.attend to an empty value will cause all commands to be paged. If pager.attend is present, pager.ignore will be ignored. To ignore global commands like :hg:`version` or :hg:`help`, you have to specify them in your user configuration file. The --pager=... option can also be used to control when the pager is used. Use a boolean value like yes, no, on, off, or use auto for normal behavior.
