Please describe the problem.

git-annex Makefile: install-completions

git-annex installs fish completions to the wrong directory. $(SHAREDIR)/fish/completions is the directory documented as being exclusive to completions which are shipped in the fish source code; third-party applications installing their own completions are intended to use $(SHAREDIR)/fish/vendor_completions.d instead.

See https://fishshell.com/docs/current/index.html#completion-path

Note that this location can also be obtained in a similar manner to bash-completion:

$ pkg-config bash-completion --variable=completionsdir
/usr/share/bash-completion/completions
$ pkg-config fish --variable=completionsdir
/usr/share/fish/vendor_completions.d

What steps will reproduce the problem?

Run "make install-completions", or install a linux distribution package of git-annex that builds with the current Makefile (Arch Linux or Debian will both show the same issue).

What version of git-annex are you using? On what operating system?

Arch Linux

git-annex 7.20191230-7

Please provide any additional information below.

Apparently this is a very common mistake :/ so far I've seen many more projects do this wrong than do it right.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Not a user, just here to help improve cross-distro packaging. :)
