Good idea to do it in cmd.exe!

Why use tee here? I did this:
C:\Users\rklemme>path >log
C:\Users\rklemme>echo exit | c:\cygwin64\bin\bash.exe --login -x -i >>log 2>&1

Same story. These are the first lines of the log
$ head -10 log | cut -c 1-80
PATH=C:\PROGRAM FILES (X86)\NVIDIA CORPORATION\PHYSX\COMMON;C:\PROGRAM FILES (X8
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
+ PATH='/usr/local/bin:/usr/bin:/cygdrive/c/PROGRAM FILES (X86)/NVIDIA CORPORATI

++ id -un
+ USER=rklemme
+ ORIGINAL_TMP=/cygdrive/c/Users/rklemme/AppData/Local/Temp
+ ORIGINAL_TEMP=/cygdrive/c/Users/rklemme/AppData/Local/Temp
The first line does not contain the dot. The fourth line contains the
dot at the end:
$ sed -nre '4s#^(.{20}).*(.{80})$#\1...\2#p' log
+
PATH='/usr/local/b...Intel/WirelessCommon:/cygdrive/c/Users/rklemme/Applications/SysinternalsSuite:.'
Concluding from the context (following lines) this is, as written
before, this line from /etc/profile:
PATH="/usr/local/bin:/usr/bin:${PATH}"
MANPATH="/usr/local/man:/usr/share/man:/usr/man:${MANPATH}"
INFOPATH="/usr/local/info:/usr/share/info:/usr/info:${INFOPATH}"
There is clearly no dot there. It's a mystery.
Wait, I tested with strace:
C:\Users\rklemme>echo exit | c:\cygwin64\bin\strace.exe -f /bin/bash
--login -x -i >str 2>&1
I found

Can anybody make sense of that? I can share the complete log with
