Documentation
The function used for opening files.
filesets-find-or-display-file ... Filesets' default function for
visiting files. This function checks if an external viewer is defined
for a specific file type. Either this viewer, if defined, or
find-file will be used to visit a file.
filesets-find-file ... An alternative function that always uses
find-file. If filesets-be-docile-flag is true, a file, which isn't
readable, will not be opened.
Caveat: Changes will take effect only after rebuilding the menu.
