Bug#795053: hashdeep: Important functions disabled by symlink removal

[if-its-not-broken-dont-fix-it at openmailbox.org]

Package: hashdeep
Version: 4.4-1
Severity: important

Dear Maintainer,

The removal of the symlinks that created the program
names md5deep, sha1deep, etc. destroys the ability of the
multi-call hashdeep progam to output and verify checksums
compatible with the equivalent GNU checksum utilities such
as md5sum, sha1sum, etc.

A simple shell session extract will illustrate this point
clearly:

$ ln -s /usr/bin/hashdeep sha1deep
$ ./sha1deep /usr/bin/hashdeep
cb1e7057d478656834c6862bab88c0870a384474  /usr/bin/hashdeep
$ /usr/bin/hashdeep /usr/bin/hashdeep
%%%% HASHDEEP-1.0
%%%% size,md5,sha256,filename
## Invoked from: [##SANITIZED##]
## $ /usr/bin/hashdeep /usr/bin/hashdeep
##
247960,b090629382bf52b7b49b1427d3b4692b,9948a73e441bedb0e87aaffca4d505dd2fd626796a9c0fdb5ca39c0d6592c3f9,/usr/bin/hashdeep

This feature is also highlighted by the author in a README
comment in Github repository for hashdeep:

"For historical reasons, the program has different
options and features when run with the names 'hashdeep'
and 'md5deep.'"

(https://github.com/jessek/hashdeep/blob/master/README.md)

Please restore the symlinks that were installed in earlier
version of the hashdeep/md5deep package (i.e. make md5deep,
sha1deep, etc. available again for direct command-line
execution)
