All of the existing answers have some quirk, so I decide to dig into the source code and see what I can come up with.

The result:

• shortcut functions and commands are disjoint.

• if you do map <key> exec "..." then it's processed with sc_exec() function in the source code, which does simple string replacement of the substring $FILE and $LINE, then forward to girara_sc_exec, which does a rudimentary parsing with g_shell_parse_argv.

  The source code of that function is at https://github.com/GNOME/glib/blob/0be6aa1b22d697bafe1991dcf47273cfcb5053be/glib/gshell.c#L661.

It does handle # as a comment character, which mean if a file name is something like ' # ' # " # " # then it's impossible to escape it properly, as far as I can see.
