First, some longer-winded way:
One of snippets I use is:

TOKEN="kilobyte:cafebabe00000000deadbeef00000000baadf00d"
org=joeblows
p=hotbabe
for (( i=1; i<=$max; i++ )); do
    if [ -e ./$i ];then T="-z ./$i";else T="";fi
    curl -u "$TOKEN" $T -sS -o "$i" "https://api.github.com/repos/$org/$p/issues/$i";
done

You want timestamping -- as, if the file is already there, it doesn't count
against the limit.  But not all parts of GitHub bear timestamps; for those,
"sleep 1" is nice as 3600/h < 5000/h.


Back to uscan:
The watch file includes only the URL, so there's no need to parse a command.
So the hack in uscan would be just:
    if the URL is github.com and $ENV{GITHUB_TOKEN}, auth as that

Yeah, it would be site-specific code which is philosophically a wrong thing
to do, but meh.


Meow!
