Mixed source and dest file using uberscripts blanks files

[anderspersson]

I know did not use the tool correct, but feel is dangerus it wipes a sourcefile!

version
babashka v1.1.173

platform
Windows 11

problem
Tested the Unberscript and mixed source and dest file witch did blank my sourcefile.
, mabe should give warning that a file with data exits ?

Directory: C:\test\bb_test

Filename: 
-a----        2023-02-09     14:32             70 source.clj

bb uberscript .\source.clj

Result:

-a----        2023-02-09     15:11              0 source.clj

Yes, I think you're right

Just a backward-compatibility question - would the plan be for the warning to actually prevent the overwrite, or just like a notice that "[filename] is about to be overwritten"? I ask because people that might be rebuilding an uberscript when they make changes could be surprised by a change in behavior (presumably having to delete or empty the target file before running their uberscript build).

@bobisageek I think we should not overwrite source files, or maybe any file that doesn't end with .jar. Overwriting a previous uberjar is fine, I think.
