That was exactly my own concern.
I wasn't aware that char-set:whitespace contains more than #\space
(display char-set:whitespace)
-> #<charset {#\ht #\newline #\vt #\np #\cr #\space}>
I should have checked that before.
Then I'll go for
(string-delete
"whatever-string"
char-set:whitespace)
upload the patch to Rietveld and post the link to the buglist.
Iiuc, that's the way to go for now.
Cheers,
Harm
