LiveScript compiler takes forever to parse a file ending with a comment containing many `#`

[robotlolita]

$ lsc --version
LiveScript 1.1.1

So, I'm not sure if the issue is with the parsing, although it's the most likely conclusion, the case is that the parsing time seems to increase a lot depending on the number of # you have at the end of your file.

The interactive prompt below shows the progression in parsing/compilation time from 25 single-line comment characters up to 28 of them:

$ printf "#########################" > test.ls
$ time lsc -cbp test.ls

real    0m0.796s
user    0m0.788s
sys 0m0.008s

$ printf "##########################" > test.ls
$ time lsc -cbp test.ls

real    0m1.483s
user    0m1.476s
sys 0m0.012s

$ printf "###########################" > test.ls
$ time lsc -cbp test.ls

real    0m2.836s
user    0m2.836s
sys 0m0.016s

$ printf "############################" > test.ls
$ time lsc -cbp test.ls

real    0m5.573s
user    0m5.580s
sys 0m0.020s

However, if the comment isn't the last line in the file, the parsing time is fine:

$ printf "############################\n" > test.ls
$ time lsc -cbp test.ls

real    0m0.116s
user    0m0.096s
sys 0m0.016s
