#136 "Unexpected at this time" error during generation

[alwyndavis]

Running NaturalDocs for the first time generated the following error:

c:\Program Files\NaturalDocs>NaturalDocs.bat -i "C:\inetpub\wwwroot\accsys-framework-ui" -o HTML "C:\inetpub\wwwroot\accsys-framework-ui_help" -p "C:\Program Files\NaturalDocs\Projects\accsys-framework-ui"
Files\NaturalDocs\Projects\accsys-framework-ui""=="" was unexpected at this time.

This was with:

• Natural Docs 1.52
• ActivePerl 5.6.13 x64
• Windows 8 x64

Fix:
Changed:

if "%1"=="" goto NOMORE
to:
if [%1]==[] goto NOMORE
