extdiff: quote user-supplied options passed to shell $ hg extdiff -p cmd -o "name <user@example.com>" resulted in a shell redirection error (due to the less-than sign), rather than passing the single option to cmd. This was due to options not being quoted for passing to the shell, via util.system(). Apply util.shellquote() to each of the user-specified options (-o) to the comparison program before they are concatenated and passed to util.system(). The requested external diff command (-p) and the files/directories being compared are already quoted correctly. The discussion at the time of changeset be98c5ce4022 correctly noted that this course of action breaks whitespace-separated options specified for external diff commands in the configuration. The lower part of the patch corrects this by lexing options read from the configuration file into separate options rather than reading them all into the first option. Update test to cover these conditions. Related changesets (reverse-chronological): - be98c5ce4022 (fix reverted to make configuration file options work) - 453097750fbf (issue fixed but without fix for configuration file)
