spaces in .bash_profile lead to "command not found"

[p at dirac dot org (Peter Jay Salzman)]

There are 4 blank lines in my .bash_profile:

   ====== start file
   echo 'BEGIN ~/.bash_profile'

   export ANT_HOME='/cygdrive/c/Java/apache-ant-1.6.5'
   export JAVA_HOME='/cygdrive/c/Java/jdk1.5.0_08'
   export CLASSPATH=''
   export EDITOR='vim'
   export PATH="${JAVA_HOME}/bin:${ANT_HOME}/bin:${PATH}"
   # export PS1='$ '


   # echo 'setting up aliases...'
   # alias ls='ls -F --color'
   # alias ll='ls -Fl --color'
   # alias la='ls -Fla --color'
   # alias lr='ls -Flr --color'
   # alias lar='ls -Flar --color'
   # alias desktop='cd /cygdrive/c/Documents\ and\ Settings/psalzman/Desktop'

   echo 'END ~/.bash_profile'
   ====== end file

Each blank line generates an error:

   $ source .bash_profile
   BEGIN ~/.bash_profile
   : command not found
   : command not found
   : command not found
   : command not found
   END ~/.bash_profile

However, if I comment all the blank lines out, I get no errors.  Each blank
line in this file seems to be causing a "command not found" error.  What
could be causing this?

Thanks,
Pete
