histedit: add proper locking around repair.strip() calls

rebase: remove second broken synopsis line (issue3172) Displaying multiple synopsis in online help has been broken since Matt RST refactoring, around ff26712a0c50. Rebase help is apparently the only one using this trick, just drop the second synopsis and assume people will understand as with graft help.

localrepo: clear the filecache on _rollback() and destroyed() This restores the old behaviour of clearing the filecache when the repo is destroyed but combines it with also clearing it on _rollback. Before, we tried to only call it through _rollback but that ruined callers of destroyed. Doing it on both code paths covers destroyed being called from somewhere else, e.g. strip.

help: add 'mergetools' alias for the 'merge-tools' help topic The '-' in 'merge-tools' is surprising but necessary in the configuration. Let's help those who forget that and are looking for help.

help: use the first topic name from helptable, not the longest alias This makes the 'additional help topics' list consistent with the output from keyword search (for instance subrepo/subrepos). The sorting by longest name was introduced in 3f6a4f1de43f. There might have been a good reason for it back then, but now it seems like a better idea to place the preferred name first in the list in helptable.

transplant: fix emptied changeset message - Append an EOL - State the changeset is skipped

transplant: handle non-empty patches doing nothing (issue2806) If patch.patch() reports patched files when applying a changeset and the following commit says nothing changed, transplant used to abort with a RuntimeError, assuming something went wrong with patching. The mismatch is patch.patch() reports patched files, not changed ones. It could be modified to report changed files but it means duplicating work from status, may be expensive in the case of binary files, and is probably not that useful at API level. For instance, if two patches are applied on the working directory, the outcome may be nothing changed while each call would have returned modified files. The caller would have to call status() itself again. This patch fixes the issue by trusting patching code: if the patch succeeded and commit reports nothing changed, then nothing changed, patch() did not "dropped changes on the floor".
