gendoc: add showtopic This function prints any topic.

gendoc: rename to showdoc from show_doc This function prints hg.1.gendoc.txt content.

check-code: automatically preppend "warning: " to all warning messages Some warnings had "warning: " at the beginning of their message. Now this is done consistent for all messages. Especially in test-check-code-hg.t it is an advantage to see warnings at once because only exceptions to them are tolerated. It is (almost) as obvious as before a6180647ea. The prefix will not remain when a warning is changed to a failure. A change like a91387a37f will not be necessary anymore.

rollback: add reference to "hg commit --amend" Now that rollback is deprecated (yay!) users might need a pointer to the alternative for 99% of the cases where I used rollback.

run-tests: generally handle line endings on windows by re Recently this regexp was only appended when running a python test. When running a tsttest there was a separate handling for each line type. Simplify and unify this.

run-tests: test for os.altsep instead of os.name when checking \ for / This tells more explicitly what it is about

hgweb: move local changelist function to the beginning of the parent one

hgweb: get rid of branchentry template duplication

merge with stable

run-tests: replace popen locking with a noop _cleanup handler on py24 This also avoids the race condition, and isn't detrimental to job scheduling.
