largefiles: use 'remote'/'local' in merge prompts like in other merge prompts
Prompts like
foo has been turned into a largefile
use (l)argefile or keep as (n)ormal file?
was not as clear as the usual prompts that use 'remote' or 'local' to explain
what happened on which side ... especially not when used to the normal prompts.
"as" could also indicate that it would be possible to take the content of the
largefile and somehow put it into the normal file. It could make it more clear
that it was a choice between one side or the other.
For consistency we will now phrase it like:
remote turned local normal file f into a largefile
use (l)argefile or keep (n)ormal file?

# 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.
