removing confusing html character codes

[dbolser]

This is motivated by the fact that ‑ is actually a different symbol from - (the minus sign on my kbd). This causes problems for simple find (Ctrl-f) in chrome, as searching for --match isnt the same as searching for ‑‑match! This could additionally cause problems when examples are coppied and pasted from the html page, i.e. "ls ‑l" gives "ls: cannot access ‑l: No such file or directory", hahahaha. Since I was getting rid of 98% the codes anyway, I went ahead and removed the other 2% for consistency as well. I imagine they just got used by a copy paste from a text editor on a mac or so...

To prove my sanity, copy paste the ‑ from the sentence "the fact that ‑ is actually" and stick it in this script:

perl -e 'print ord("‑"), "\n"'
# 226

and do the same for the - from the sentence "different symbol from - (the minus sign on my kbd)":

perl -e 'print ord("‑"), "\n"'
# 45

Confusing eh?
