reduce number of Unicode private-use characters

Browse Source 
This narrows the range of Unicode codepoints fish reserves for its own
use from U+E000 thru U+F8FE (6399 codepoints) to U+F600 thru U+F73F (320
codepoints). This is still not ideal since fish shouldn't be using any
Unicode private-use codepoints but it's a step in the right direction.

This partially addresses issue #2684.

\section faq-reserved-chars Unicode private-use characters reserved by fish
Fish reserves the <a href="http://www.unicode.org/faq/private_use.html">Unicode private-use character range</a> from U+F600 thru U+F73F for internal use. Any attempt to feed characters in that range to fish will result in them being replaced by the Unicode "replacement character" U+FFFD. This includes both interactive input as well as any file read by fish (but not programs run by fish).
