I always fix it this way, while the file is open:
:%s/\r//
:set ff=dos
:w
As for what causes it, Vim is perfectly capable of detecting DOS/
Windows-style line endings, but only if _every_ line in the file has
them. If even 1 line does not have the proper line ending, the file is
treated as Unix so that you can see all the contents of the file.
Many editors in Windows have been designed so that when pasting lines
from a file with one style of line ending into a file with another
style, no conversions will be made. This is probably the most frequent
source I've seen for the problem. Someone will copy some lines from a
Unix-style file into a Windows file, and not realize what happened
because their editor cannot differentiate between the two line
endings. Visual Studio I think just does this blindly. Ultraedit has a
setting (disabled by default!) that will automatically convert the
line endings. Other editors may or may not do things more
intelligently depending on their settings.
