Micro fails to set correct mime-type for clipboard copy from perl files.

Micro specifies only application/x-perl mime-type and no text/plain for text copied from file that starts with #!/usr/bin/perl or #!/usr/bin/env perl.
Example file:

#!/usr/bin/perl

gives

$ wl-paste --list-types
application/x-perl

Correct behavior can be seen for bash files:

#!/usr/bin/bash

gives

$ wl-paste --list-types
application/x-shellscript
text/plain
text/plain;charset=utf-8
TEXT
STRING
UTF8_STRING

note: foo.pl/foo.sh without shebang give

$ wl-paste --list-types
text/plain
text/plain
text/plain;charset=utf-8
TEXT
STRING
UTF8_STRING

(with duplicate text/plain)

Note: i hadn't tested many shebangs, maybe issue is not exclusive to perl scripts.

micro -debug does not show anything

micro version: 98ff79dbcaff3df2f70e4c322f0b3d406f6ae698
environment: wayland

Reproduce the report under Wayland with the shown Perl shebangs, using wl-paste --list-types, and compare the output with the bash example. Trace Micro's clipboard MIME-type handling from the copy action; done means Perl copies include text/plain and related text types without regressing the existing behavior.
