Compact output is not compact enough

[relet]

I would like to have an option (-cc ?) that actually minifies the output. Strip whitespace, print integer-ish numbers as integer, possibly specify float precision.

I'll add an option to remove whitespace, or maybe just make the existing -c do that. Numbers are already printed as small as they can be - the rendered text is the shortest string which, after round-to-nearest-double, produces the original input.

So, integers are already printed as integers. If you divide 1 by 10, the internal double is actually about

0.10000000000000000555

However, the string "0.1" is shorter and rounds to the same double value, so that's printed instead. (this isn't my code, go look at dtoa.c on netlib if you want wayyyyy too many details).
