These PowerShell related extensions are text files, so if they are regarded as binary in BitBucket, then please make them text:

• .PS1 – Windows PowerShell shell script
• .PSD1 – Windows PowerShell data file (for Version 2)
• .PSM1 – Windows PowerShell module file (for Version 2)
• .PS1XML – Windows PowerShell format and type definitions
• .CLIXML - Windows PowerShell serialized data
• .PSC1 – Windows PowerShell console file
• .PSSC - Windows PowerShell Session Configuration file

See: https://en.wikipedia.org/wiki/Windows_PowerShell#File_extensions

Notes:

1. the extensions are case insensitive (I know that Git and Mercurial/HG are case sensitive, so it might be needed to include the permutations of uppercase/lowercase letters in these extensions)
2. often these files are stored with Unicode BOM U+FEFF (as edited by either PowerShell ISE, PowerGUI, NotePad or other Unicode aware text editors)

An example file that fails is mentioned at https://answers.atlassian.com/questions/330206/why-is-this-ps1-file-being-downloaded-from-my-hg-repository and available from https://bitbucket.org/jeroenp/besharp.net/src/b356056dbf9189ec8297aeaa5575f8e4092fba65/Scripts/NoIP/Login-and-Update-NoIp.ps1
