Added tag 3.2.2 for changeset 902554884335

merge: before cd/dc prompt, check that changed side really changed Before, merging would in some cases ask "wrong" questions about "changed/deleted" conflicts ... and even do it before the resolve phase where they can be postponed, re"resolved" or answered in bulk operations. Instead, check that the content of the changed file really did change. Reading and comparing file content is expensive and should be avoided before the resolve phase. Prompting the user is however even more expensive. Checking the content here is thus better. The 'f in ancestors[0]' should not be necessary but is included to be extra safe.

largefiles: don't show largefile/normal prompts if one side is unchanged

tests: add test-issue3084.t cases for 'changed but same' as for 'unchanged' Use suffix -same for cases where file changed but content is the same - that is the case where manifestmerge doesn't detect that a file is unchanged. (The suffix -id is already used for cases where the file didn't change - that is the trivial case where manifestmerge detects that the file is unchanged.) These new tests are good but the results are bad. There shouldn't be any merge conflicts or prompts when one side didn't change.

tests: clean-up of largefiles tests in test-issue3084.t Prepare for adding more test cases to the systematic testing, moving the test from ac3b3a2d976d to another section.

pushkey: gracefully handle prepushkey hook failure (issue4455) This allow to gracefully report the failure of the bookmark push and carry on. Before this change set. Local push would plain quit and wireprotocol would failed in various ungraceful way.

hook: raise a more specialized HookAbort exception when a hook fails We need to gracefully handle some aborts for pushkey, especially because it leads to a user-facing crash over the wireprotocols. So we need a more specialized exception to catch.

help: fix typo in files help

revset: fix first and last for generatorset (issue4465) The code was just plain wrong.

mq: fix update of headers that occur in the "wrong" order Mq tried to insert headers in the right order. Sometimes it would stop searching before checking all headers and it could thus duplicate a header instead of replacing it.
