[bug#49581] [PATCH v4] gnu: Add git-issues.

[phodina]

Hi,

Thanks Sarah for the feedback and tips on how to wrap the programs in the shell 
script.

In fact the patch is almost done, but I couldn't figure out the correct 
procedure for the map on line 1324. I get that the list of strings should be 
mapped into paths to the binaries, but after struggling I gave up and found 
book about Scheme to learn first.

So here is the patch with the minor issue.

Hope this utility helps.
