inconsistent behaviour with checker and create-text

[bremner]

I'm not sure if this is intended, but it's confusing, at least to me.

I have

(define allow-submit-on-error?  #t)

in info.rkt. When I submit files that fail user defined checks (in this case a missing identifier), the text version is written as expected. When I submit files with lines longer than maxwidth, the grading directory is not created and the text version of the file is not written.

I don't completely understand the code, but it looks like the width check happens earlier than user defined checks. It's not like it's terribly hard for students to meet the line length constraints, but if it is a harder constraint it would be good to document, so admins don't get confused into thinking no text versions at all are being created on errors.

I vaguely remember the maximum width thing being implemented at the level that converts the wxme file into text, so that error is probably taken as other conversion errors and therefore no text version is made. It would probably be easy to avoid that error when the parameter is on, but I'm guessing that you'll want something in the file that indicates it rather than just ignoring it (otherwise you could turn the width checking off) -- and that's probably more involved...
