New command to export a patch and allow existing log command to take options. * Hglogexport command takes patch name as input. If the env variable HG_EXPORT_PATCH_DIR is set, then the patch will be created under it. Otherwise, it will be created in the directory from which vim was launched. * HgLog command takes options that can be passed to hg log command. E.g., the following command will list just 3 logs by user bob. :Hglog -u bob -l 3 Testing: * Patch gets created under the right directory when env variable is set and not set. * Hglog command honors -u and -l options. It also works when current file name is given as input --> :Hglog % -u bob -l 3
