convert: backout 81cf597dafa9 and a3545c3104aa -closemap
Closemap solves a very specific use case. It would be better to have a more
generic solution than to have to maintain this forever.
Closemap has not been released yet and removing it now will not break any
backward compatibility contract.
There is no test coverage for closemap but it seems like the same can be
achieved with a simple and much more powerful custom extension:
import hgext.convert.hg

c = super(source, self).getcommit(rev)

# pager.py - display output using a pager # # Copyright 2008 David Soria Parra <dsp@php.net> # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. # # To load the extension, add it to your configuration file: # # [extension] # pager = # # Run "hg help pager" to get info on configuration. '''browse command output with an external pager To set the pager that should be used, set the application variable:: [pager] pager = less -FRX 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. 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.
