Incorrect path when opening emacs through the emacs.app application icon

[amicitas]

emacs-app @26.1_3

When opening Emacs through the /Applications/MacPorts/Emacs.app, the PATH environment is incorrect. Rather than using the macports path, the default system path is used.

If I run Emacs from a terminal window by typing the command /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs, the path environment is ok.

Expected:

M-! which ssh -> /opt/local/bin/ssh

Actual:

M-! which ssh -> /usr/bin/ssh

This problem does not exist in emacs-app @25.3_0; after activating that older version the paths is correct. The problem exists in both @26.1_2 and @26.1_3 (other versions not tested).

In the future, please use WikiFormatting and add the port maintainer(s) to Cc (port info --maintainers emacs-app), if any.

Adding the following lines to Emacs.app/Contents/Info.plist resolves this issue:

        <key>LSEnvironment</key>
        <dict>
                <key>PATH</key>
                <string>/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
        </dict>

(Tested with emacs-app-devel @20181216)

emacs-app(-devel): set PATH when starting app to include MacPorts prefix

Stop using a separate revision for emacs and emacs-app to simplify the
portfile.
