When amfora is given a string to search, if that string contains a
valid protocol (gemini://), and that string contains trailing
whitespace, then the string is treated as a search term.
Although perhaps slightly more uncommon, if the input string was as a
result of copy/paste then it's possible the string could contain
trailing spaces, which is not what was intended, but rather should be
removed so that it's treated either as a valid gemini:// link or a
search term.
Some efforts around this appeared in #138
