I'm sorry, but there was an error in the script I just posted.
(a leftover line that add extra u to the mount flags).
Seeing an email by cgf I enhanced my script to quote the Paths.
The script takes some times, so I added echos to stderr.
So here is the new script:

------------------------- mount-export.sh -------------------------

#! /bin/sh -e
# Export the current mount into a script to rebuild it
# the script is written into $1 (stdout if none/empty)
# ----------------------------------------------------

quote ()                                   # quote stdin to stdout
{                                          # change \ to \\, " to \"
   sed -e "s/\\\\/\\\\\\\\/g"  \
       -e "s/\\\"/\\\\\\\"/g"  \
       -e "s/\`/\\\\\\\`/g"              # re-escape \, ", ' and `
}
# ----------------------------------------------------------------------

dcd_ln ()                                  # decode 1 mount line
{                                          # given as argument

    WINP=`echo $1 | cut "-d " -f1 | quote` # Windows Path (unquoted)
    MNTP=`echo $1 | cut "-d " -f2 | quote` # Cygwin mount point
    U_S=`echo $1 | cut "-d " -f3`          # user / system
    BTX=`echo $1 | cut "-d " -f4`          # binmode / textmode , exec

    FLAGS="-f"
    case "$U_S" in
        "user" )   U_S=u   ;;              # user mount
        "system" ) U_S=s   ;;              # user mount
           *  )    echo "Error, type is $U_S, should be user/system !"
                   exit 1  ;;              # grave error
    esac

    case "$BTX" in
        *"exec" )  FLAGS="${FLAGS}x" ;;    # mounted with exec[ute]
    esac

    case "$BTX" in

        "text"* )  BTX=t   ;;              # mounted in text mode
           *  )    echo "Error, flags are $BTX, should be binmode/textmode !"
                   exit 1  ;;              # grave error
    esac
    FLAGS="$FLAGS$U_S$BTX"                 # flags for mount
}
# ----------------------------------------------------------------------

add_mounts ()                              # work on current mounts
