mergetool: use path to mergetool in config var mergetool.<tool>.path
This commit adds a mechanism to provide absolute paths to the external programs called by 'git mergetool'. A path can be specified in the configuation variable mergetool.<tool>.path. The configuration variable is similar to how we name branches and remotes. It is extensible if we need to specify more details about a tool. The mechanism is especially useful on Windows, where external programs are unlikely to be in PATH.

You can explicitly provide a full path to the tool by setting the
|
||||
configuration variable mergetool.<tool>.path. For example, you
|
||||
can configure the absolute path to kdiff3 by setting
|
||||
mergetool.kdiff3.path. Otherwise, 'git mergetool' assumes the tool
|
||||
is available in PATH.
