patch: ensure valid git diffs if source/destination file is missing (issue4046) This is arguably a workaround, a better fix may be in the repo to ensure that it won't list a file 'modified' unless there is a file context for the previous version.

histedit: add description about exit code

rebase: add description about exit code when there are unresolved conflicts

shelve: remove unused variable assignment Fix test-check-pyflakes.t error after 1d7a36ff2615. This patch replaces "readshelvedfiles()" invocation by "shelvedfile().exists()" check and aborting, because it is required only to ensure that shelved changes corresponded to specified name exist after invocation. This patch also remove definition of "readshelvedfiles()" itself, because it is invoked only from the line removed by this patch.

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?
