url encode docs: mention '-', '.', '_' and '~'

Browse Source 
Clarify that the '-', '.', '_' or '~' letters are also not escaped since
they shouldn't according to RFC3986 section 2.3.

This is how this function has behaved since sep 2010, commit
5df13c31735fa0.

.SH DESCRIPTION
This function converts the given input string to an URL encoded string and
returns that as a new allocated string. All input characters that are not a-z,
A-Z or 0-9 are converted to their "URL escaped" version (%NN where NN is a
two-digit hexadecimal number).
A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped" version
(%NN where NN is a two-digit hexadecimal number).
If the \fBlength\fP argument is set to 0 (zero), \fIcurl_easy_escape(3)\fP
uses strlen() on the input \fBurl\fP to find out the size.
