awk error

[ppKrauss]

Hi, a "standard pretty JSON" is very important, as "easy diff" and "universal human-readability", so canonicalJSON + prettyjson is a good solution, even for digital preservation.

Using chmod 777 prettyjson.awk and ./prettyjson.awk file.json at UBUNTU 16 LTS, it is causing error
"awk: run time error: regular expression compile failed (missing operand)".

PS: a complement for prettyjson is, for checksums, to pipe with some stripSpaces.awk before hash generation.

Thanks for the report; I've confirmed the awk incompatibility and am fixing it now.
