improved the description of the -L/--location option

If this option is used twice, the second will again disable list only.

.IP "-L/--location"

(HTTP/HTTPS) If the server reports that the requested page has a different

location (indicated with the header line Location:) this flag will let curl

attempt to reattempt the get on the new place. If used together with

\fI-i/--include\fP or \fI-I/--head\fP, headers from all requested pages will

be shown. If authentication is used, curl will only send its credentials to

the initial host, so if a redirect takes curl to a different host, it won't

intercept the user+password. See also \fI--location-trusted\fP on how to

change this.

(HTTP/HTTPS) If the server reports that the requested page has moved to a

different location (indicated with a Location: header and a 3XX response code)

this option will make curl redo the request on the new place. If used together

with \fI-i/--include\fP or \fI-I/--head\fP, headers from all requested pages

will be shown. When authentication is used, curl only sends its credentials to

the initial host. If a redirect takes curl to a different host, it won't be

able to intercept the user+password. See also \fI--location-trusted\fP on how

to change this. You can limit the amount of redirects to follow by using the

\fI--max-redirs\fP option.
