relax jslint-warning against space-character in regexp?

[kaizhu256]

@douglascrockford, i frequent regexp-use-cases where the space-character is explicitly specified, e.g.

~/Downloads/jslint$ git grep u0020
.ci.sh:        /\n```shell\u0020<!--\u0020shRunWithScreenshotTxt\u0020(.*?)\u0020-->\n([\S\s]*?\n)```\n/g
.ci.sh:        /\n\n#\u0020(v\d\d\d\d\.\d\d?\.\d\d?(.*?)?)\n/g
.ci.sh:                /^let\u0020jslint_edition\u0020=\u0020".*?";$/m
index.html:            /^([^\n\u0020@].*?)[,{:].*?$/gm
index.html:                /^0\u0020(?:(body\u0020>\u0020)?(?:\.button|\.readonly|\.styleColorError|\.textarea|\.uiAnimateSlide|a|base64|body|code|div|input|pre|textarea)(?:,|\u0020\{))|^[1-9]\d*?\u0020#/m
jslint.mjs:                    /^\u0020{4}at\u0020(?:file|stop|stop_at|test_cause|warn|warn_at)\b.*?\n/gm

jslint.mjs:                    warn_at("expected_a_b", line, column, "\\u0020", " ");
jslint.mjs:        /\n(?:\*\u0020\[`|##\u0020|##\u0020Class:\u0020)`\w+/g
jslint_ci.sh:        /\n#\u0020Table\u0020of\u0020Contents$[\S\s]*?\n\n\n/m
jslint_ci.sh:            /\n\n\n#\u0020(.*)/g

jslint_ci.sh:                /\u0020/g

jslint_ci.sh:            /^(\S+)\u0020(.*?)\n/
jslint_ci.sh:                    /^git\u0020/
jslint_ci.sh:            /[\t\u0020]+$/gm
jslint_ci.sh:            /\n+?(\n\u0020*?\})/g
jslint_ci.sh:            /\n\/\*\nfile\u0020none\n\*\/\n\/\*jslint-enable\*\/\n([\S\s]+)/
test.mjs:                /\u0020{4}/g
test.mjs:        /(\n\s*?\/\/\s*?test_cause:\s*?)(\S[\S\s]*?\S)(\n\n\s*?)\u0020*?\S/g
test.mjs:            /^\/\/\u0020/gm
test.mjs:            /\u0020\/\/jslint-quiet$/gm

and would like to improve regexp-readability (and jslint's user-friendliness) by allowing space instead of \u0020. what are your thoughts on this?

was the original-intent of disallowing space to prevent confusion with <tab>? if so, jslint already forbids <tab> in code anyways:

[douglascrockford]

Improving regexp-readability is a lost cause.

Do what you think best.

k, intend to relax the rule then.

fyi, warning was relaxed in pr-362
