multiline command parsing

what's explanation keeps

[system.enum]::getvalues([`

system.serviceprocess.servicecontrollerstatus`

])

from parsing same as

[system.enum]::getvalues(`

[system.serviceprocess.servicecontrollerstatus]`

)

in second example not actualy need escape newlines. ;)
re: why ps not understand first one:
guess need have complete tokens e.g.:

g`
wmi

won't work either - backtick not cure linebreak. same with:

[system.enum]:`
:getvalues(

while:

[system.enum]::`
getvalues(

works. can use tokenizer see parts can't broken linebreaks , glued backtick:

[management.automation.psparser]::tokenize('[system.enum]::getvalues([microsoft.powershell.executionpolicy])', [ref]$null)
