[tex-k] tangle.web: '.' -> `.'

[胡亚捷 (Hu Yajie)]

tangle.web, line 640 (section 31, the first Pascal comment):
    procedure error; {prints '\..' and location of error message}
should be
    procedure error; {prints `\..' and location of error message}

(Interestingly, the same typo has been fixed in weave.web.)




To karl: you might also want to change newbug.html, line 200

to
