Ensure that line-breaks are *only* skipped after operators in Lexer.getNumber (PR 8359 follow-up)

Browse source 
With the current code line-breaks are accepted not just after an operator, but after a decimal point as well. When looking at this again, the latter case seems prone to cause false positives and might also interfere with subsequent patches.

Hence this is code is adjusted to actually do what the original commit message says, and nothing more.
